Anti-sliding batten with preventing thermal expansion and its manufacturing method

ABSTRACT

The present invention discloses that an anti-sliding batten with preventing thermal expansion being applied on that setting up a shield on a roof with the batten and comprising a plurality of projecting blocks spread on at least one surface of the batten with a suitable interval for any two adjacent projecting blocks. By means of the present invention, the friction between the anti-sliding batten and the shield is increased, hence two of them are tightly touched each other for promoting working safety; further, careless workers being sliding to fall down is then prevented and the phenomena of shrink and expansion are no longer exist.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention generally relates to an anti-sliding batten with preventing thermal expansion and its manufacturing method, especially an improved structure of the anti-sliding batten for applying onto a roof. It is mainly to adopt that covering a shield in a roof and fixing the shield thereon by means of the anti-sliding batten.

[0003] 2. Description of the Prior Art

[0004] Traditionally, a batten for covering and fixing a shield on a roof is a simple structure, and it is shaped as a long strip with a smooth surface and positioned on the roof by means of plural screws. Actually the traditional batten is easily to be manufactured, but it is hard to stand long enough for weather. For example, the batten is always curved by high temperature in a hot season because of thermal expansion. On the other hand, due to the batten continuously shrinking and expanding day and night, the screws are loose gradually, and the shield finally is taken off from the roof. Another condition is that the shield is broken or not on its original position, since the two causes of weather and a small friction between the shield and the smooth of the batten.

[0005] Today, everything being issued to safety lets the prior art be not competitive. The reasons of the simple structure and the smooth surface possibly cause a sliding action to make a worker injured.

SUMMARY OF THE INVENTION

[0006] The main objective of the present invention is to offer an anti-sliding batten with preventing thermal expansion and its manufacturing method to have a function of anti-sliding, therefore sliding actions for a worker and a shield covering on a roof are prevented. The shield is normally a light shield, a plastic protection, an ambient light hood or a heat insulation plate.

[0007] Other and further features, advantages and benefits of the invention will become apparent in the following description taken in conjunction with the following drawings. It is to be understood that the foregoing general description and following detailed description are exemplary and explanatory but are not to be restrictive of the invention. The accompanying drawings are incorporated in and constitute a part of this application and, together with the description, serve to explain the principles of the invention in general terms. Like numerals refer to like parts throughout the disclosure.

DETAILED DESCRIPTION OF THE INVENTION

[0015] Referring to FIG. 1A, 1B, 1C and 1D, which are the first preferred embodiment of the present invention. FIG. 1A is a top view of an anti-sliding batten of the present invention. FIG. 1B is a bottom view of the anti-sliding batten of the present invention. FIG. 1C is a side view of the anti-sliding batten of the present invention. FIG. 1D is another enlarged side view of the anti-sliding batten of the present invention.

[0016] Based on the aforesaid drawings, the features of the present invention are a plurality of projecting blocks 102 and 103 on each surface of an anti-sliding batten 10 of FIG. 1A and FIG. 1B. Any two projecting blocks have a suitable interval.

[0017] Each of the projecting blocks 102 and the projecting blocks 103 is shaped as a quadrilateral.

[0018] Referring to FIG. 2, which is a flow chart of manufacturing the anti-sliding batten of the present invention. Firstly, a first step 20 of the flow chart is to cut a first seam, as a first seam 104 in FIG. 1A and another first seam 105 in FIG. 1B, along a cutting direction, as a cutting direction 12 in FIG. 1A and another cutting direction 16 in FIG. 1B. Continuously, a second step 22 of the flow chart is to cut a second seam, as a second seam 106 in FIG. 1A and another second seam 107 in FIG. 1B, along another cutting direction, as a cutting direction 14 in FIG. 1A and another cutting direction 18 in FIG. 1B; the second seam is intersected the first seam. A third step 24 of the flow chart is to repeat aforesaid two steps.

[0019] The material for the present invention adopts a plastic compound plate. After going through the above steps, the entire first seams 104 in FIG. 1A and all of the first seams 105 are parallel each other and spread on the anti-sliding battens 10 of FIG. 1A and FIG. 1B with suitable intervals, and same theory with the second seams 106 in FIG. 1A and the second seams 107 in FIG. 1B. The embodiments may not be like aforesaid; the projecting block can possibly be as a shape of triangular, polygon or irregularity.

[0020] To conclude the features of the present invention, the following is the list:

[0021] 1. By means of the projecting block of the anti-sliding batten, the friction between the anti-sliding batten and the shield is increased, hence two of them are tightly touched each other. Further, careless workers' are being sliding to fall down is then prevented.

[0022] 2. Due to suitable intervals among the seams 104, 105, 106 and 107, a deflection phenomenon of a thermal expansion effect is totally avoided. Referring to FIG. 3, which is a sketch of variable conditions of the anti-sliding batten in expansion of the present invention. The two projecting blocks 103 are expanded outward (shown as dot-lines) to make a shorter interval. There is a room, the first seam 105, to contain the expanded parts of the two projecting blocks 103, and therefore the phenomena of shrink and expansion are no longer exist.

[0023] 3. The material of the present invention accepts a plastic compound with thermoset, convenient machining, better anti-damaging, long life and recycling. Thus it is obviously that the present invention is full of the concept of environment protection.

[0024] Although this invention has been disclosed and illustrated with reference to particular embodiments, the principles involved are susceptible for use in numerous other embodiments that will be apparent to persons skilled in the art. This invention is, therefore, to be limited only as indicated by the scope of the appended claims.
